With non-blocking pool restricted by 10 in capacity, the probability of
dropping events is unexpectedly big. Notifications are an essential part of the FrostFS,
we should not drop anything, especially new epochs.

Make it store its internal `zap.Logger`'s level. Also, make all the
components to accept internal `logger.Logger` instead of `zap.Logger`; it
will simplify future refactor.

Storage node can be requested to be switched into `MAINTENANCE` state.
Inner Ring should accept such requests only if network configuration
allows it.
Make `Processor` of Netmap contract's notifications to depend on
`state.NetworkSettings`. Make `Processor.processUpdatePeer` to call
`MaintenanceModeAllowed` if notification event relates to `MAINTENANCE`
mode`. Share singe `state.NetworkSettings` provider in Inner Ring
application.

There is a need to prevent limitless abuse of MAINTENANCE status of the
storage nodes. To do this, configuration of the NeoFS network is going
to be extended with the flag which allows the state. Until this is done,
it makes sense to prepare a site for this in the code.
Define `state.NetworkSettings` interface as an abstraction of global
network configuration within the `state` package. Make
`NetMapCandidateValidator` to depend on `NetworkSettings` and provide
corresponding field setter. Change `VerifyAndUpdate` method's behavior
to return an error for candidates with MAINTENANCE state if this state
is disallowed by the network configuration. Provide `NetworkSettings`
from the wrapper over Netmap contract's client on Inner Ring application
side. The provider is implemented to statically disallow MAINTENANCE
mode in order to save previous behavior.

In previous implementation Inner Ring allowed storage nodes with any
state to register in the network. According to the current design, only
nodes with ONLINE state are allowed to enter the network map.
Create new `state` sub-package of `nodevalidation` package of Inner Ring
application. Define `state.NetMapCandidateValidator` type and provide
`NodeValidator` interface required by the Inner Ring's processor of
`Netmap` contract's notification events. Embed new validator into the
one used by the Inner Ring application.
From now all `AddPeer` notifications with node state other than `ONLINE`
will be denied.

Return listen errors in a synchronous fashion.
Another solution would be to use buffered channel, but this is not
scalable: for each new similar runner we would need to extend the
buffer.

Add worker pool to the listener to prevent blocking. It is used only for
notary notifications and new block events handling since it uses RPC
calls. That may lead to the deadlock state: neo-go cannot send RPC until
notification channel is read but notification channel cannot be read since
neo-go client cannot send RPC.

Provide current heights as an argument to ticker.
Zero height disables any checks, thus corresponding to the old
behaviour. If non-zero height is used, ignore the tick if the height
is less than the timer tick state.

When IR node configured without main chain, both
`morphListener` and `mainnetListener` are pointing
into single listener component. We should not call
`Stop()` twice, because it may trigger channel
closing in neo-go or other components and it
can throw panic.

If mainchain is disabled in IR config then the node should read inner
ring list via role management contract.
Use `NeoFSAlphabetList` method of morph client as IR lister if
`withoutMainNet` flag is set in IR app.

In notary disabled environment, approval of container creation with nice
name attribute takes much more additional GAS than other operations
(due to NNS invocation).
Morph library changes:
* add the ability to specify per-op fees using `StaticClient` options;
* add the ability to customize fee for `Put` operation with named
container in container morph client.
Inner Ring changes:
* add `fee.named_container_register` config value which specifies
additional GAS fee for the approvals of the named container
registrations;
* pass the config value to `WithCustomFeeForNamedPut` option of
container morph client.
